What GMA does

GMA Metall GmbH is a German precision metal parts manufacturer headquartered in Bünde-Ahle, Germany, with a second production facility in Kaplice, Czech Republic, employing approximately 315 people. Originally founded in 1962 as a family-owned Mittelstand company under Kurt Meyer, GMA was acquired by ISRINGHAUSEN GmbH & Co. KG in September 2017 and is now a subsidiary within the AUNDE Group, a global automotive supplier group operating 127 production facilities across 29 countries. The company produces custom drawn, stamped, fine blanked, and bent metal components, serving the automotive, electrical/electronics, and fine mechanics industries on a B2B contract manufacturing basis.

The company's core technology is fine blanking (Feinstanzen), operating more than 40 fine blanking automatons with press forces ranging from 80 to 3,600 tons, alongside 20+ hydraulic and mechanical standard stamping presses ranging from 32 to 1,000 tons. A distinguishing technical capability is the ability to perform fine blanking combined with press compound operations, executing embossing, cutting, and bending in a single process stroke to produce parts with practically parallel cut surfaces and tight tolerances. GMA operates dedicated 500-ton and 1,000-ton presses for non-ferrous metals (aluminum and stainless steel) to eliminate ferrous contamination risk, plus comprehensive in-house secondary processing including welding (MIG, MAG, WIG, resistance spot), heat treatment, machining, grinding, vibratory finishing, and pickling. The company maintains 44 employees in tool construction and machine construction, enabling fully in-house tooling development.

GMA generates revenue through direct sales of custom-manufactured precision components under quote-based pricing tied to part specifications, materials, tolerances, volumes, and complexity, with multi-year supply contracts typical for automotive customers. The go-to-market is sales-led, targeting automotive OEMs and Tier 1/2 suppliers, electrical equipment manufacturers, and fine mechanics companies through direct technical consultation. Quality credentials include ISO/TS 16949 for automotive, ISO 14001, and EMAS registration. Following the 2017 acquisition, the company is positioned within AUNDE Group's broader automotive supplier ecosystem alongside ISRINGHAUSEN (seating and springs), FEHRER (interior modules), and REINERT (technical plastics), but GMA itself retains a regional European operational footprint with no public revenue disclosure.

Core offering

GMA manufactures custom precision metal components including drawn, stamped, fine blanked, and bent parts for the automotive, electrical, and fine mechanics industries. The company operates four core production capabilities at sites in Germany and the Czech Republic: fine blanking, standard blanking, system manufacturing (welding, heat treatment, machining, surface finishing), and in-house tool and machine construction. Production processes steel, stainless steel, and aluminum up to 15 mm thickness across over 40 fine blanking automatons and 20+ standard stamping presses.

Product overview

GMA is a precision metal parts manufacturer offering a vertically integrated production portfolio. The core offerings include Feinstanzen (Fine Blanking) for high-precision parts with near-burr-free surfaces on over 40 fine blanking presses (80-3,600 tons), Normalstanzen (Standard Blanking) using 20+ hydraulic/mechanical presses (32-1,000 tons), Systemherstellung (System Manufacturing) for assembly, welding, heat treatment and surface finishing, and Konstruktion/Werkzeugbau (Construction & Tool Building) with 32 toolmakers and 12 machine builders supporting all production operations. The company produces drawn, stamped, fine blanked, and bent parts primarily for automotive, electrical, and precision engineering industries at locations in Germany (Bünde) and Czech Republic (Kaplice).

Products and services

• Fine Blanking (Feinstanzen) Fine blanking and fine cutting production of precision metal parts with nearly burr-free workpieces, smooth perpendicular cut surfaces, and very high flatness requirements. GMA produces fine blanked parts with practically parallel cut surfaces in a single working stroke, including press compound operations combining embossing, cutting, and bending. Production runs on over 40 fine blanking automatons with press forces from 80 to 3,600 tons. Targeted at automotive, electrical, and fine mechanics industries requiring tight tolerances.
• Standard Blanking (Normalstanzen) Standard blanking production using more than 20 hydraulic and mechanical presses with press forces from 32 to 1,000 tons. Equipped with single and double-acting drawing devices, table sizes up to 4,000 x 2,200 mm with maximum strip width of 1,400 mm. Includes dedicated non-ferrous metal processing (aluminum and stainless steels) on 500-ton and 1,000-ton presses without risk of ferritic contamination. Materials processed include steel, stainless steel, and aluminum up to 15 mm thickness.
• System Manufacturing (Systemherstellung) Further processing of blanked parts including welding (MIG, MAG, WIG, and resistance spot welding), heat treatment in bell-type furnaces and induction hardening, machining including honing and lapping, band grinding and double-disc grinding, surface treatment with seven vibratory finishing troughs and two vibratory finishing systems with automatic packaging, as well as pickling and washing. Delivers finished or semi-finished assemblies to industrial customers.
